What Is Galvanized Steel Pipe?

Galvanizing steel involve immersing steel in hot zinc via an electroplating process known as galvanizing to prevent the steel from rusting. Our pre galvanized steel can go through the process if the customer sees the need for it.

The zinc coating will prevent the steel core from corroding by serving as a protective outer layer. In addition, zinc in low quantities is not toxic to humans, and that makes it an ideal metal for coating water pipes.

When compared to lead pipes, which are decidedly much more toxic, the use of galvanized pipes represented a major advance in indoor plumbing. However,Copper pipes have replaced the use of galvanized steel pipes in most new home construction.
